Scrble Ink is an extremely simple app for freehand writing on Windows tablets. Scrble's inking is responsive and fun. You can ink with a pen or a finger and use two fingers to enlarge or move the selection. You can import images or PDFs to annotate, convert your writing to text or use geometric shapes to annotate your drawings. Scrble Ink works on all types of touchscreens, but it's especially fun with a digitized pen like the Microsoft Surface Pen. I suggest you watch this short video to see Scrble Ink in action: http://www.scrble.com/introducing-scrble-ink Thanks for your interest and I wish you happy scribbling.
